Feature #4513

allow whitespace following EOL continuation backslash

In a few programming languages, the displayed or printed program can hide
critical syntactic and/or semantic information. For example, in make(1)
and Python, the difference between initial tabs and spaces can cause bugs
that are not visually apparent.

Ruby has a minor instance of this problem, in that spaces or tabs
between a backslash and the EOL will prevent the line from being continued:

a \
?> = 2
=> 2
b \
SyntaxError: compile error
(irb):3: syntax error, unexpected $undefined, expecting $end
from (irb):3

Could Ruby open up its syntax to allow any number of intervening spaces or tabs before the EOL?

Regardless it's acceptable or not, we want to check nobu's local patches first. Don't you have that?

  • Priority changed from Normal to 3

It is easy to change, but I doubt if it is useful.
